The third in my series on missing numbers on a number square which can be found in the Year 2 Counting category. Each grid shows a different section from a 1-100 number grid, with only a couple of the numbers filled in. The task is to complete the number grid.

This is very good practice at counting on and back in ones, from any 2-digit starting number. It is also very good at showing the patterns in numbers, for example by moving down the grid one space the number increases by ten.
